This invention relates to weather sealsfor windows of the type in which the jambs have vertlcal openings through their inner face which lead to enlarged chambers within the 5 iambs and thesashes have plates which extend intothese openings, and involves a modification of or improvement upon the construction shown in Campbell 'Patent llos lfifiq;

'393, issued June 12, 1928. With windows of portion or break in the sill about in line with the inside edge of the vertical opening prodownwardly so that thelower sash extends.

down outside of such break. A detailed showing of a sill construction in whichthis break is particularly apparent is found in Campbell application, Ser. No. 375,384, filed July 2,1929. I 1 1 I lVhere the window is exposed to heavy wind pressures as in, modern high buildings, there is danger, in the event of 'a driving'rain storm, that water will be'driven around the ends of the lower sash plates and run to; the fiat portion of the sill whichjextends into the jamb, and then leak throughinto the'room. By my present invention I. provide a construction which overcomes this diiiiculty. Inasmuch as the construction is primarily intended for the lowersash of the window,I have illustrated it only in this connection, but

'fupper sash if occasion should demand.

My invention may be readily understood by v indoors portion of the inner jamb wall which is bent outwardly as shown at 4 to contact with the partition member 6 in the'jamb. At-

It then is bent to contact once more withthei sash plate lO'and has an extension which runs 7 fbet'ween member ld and the rearface of baffle 8; It is to be understoodthat member 18 is connected with sash plate 10 so that it will move vertically withthesash plate,but may move horizontally relative tothejsash plate.

Such a method 'ofconnection is shown inthe intofthe jamb, it must follow either one of If it forces the extending portion of member 18 "away from the rear of baflle 8, it cannot get around the'sash plate10,v for members l8and 14 will be in spring con tact. There isfarmore danger of the water following around theface of the sash'j between the sash and member 18,'but in this case the water will enter the enlarged chamber in front of the extended portionof angle16,

where the air will tend to loseits velocity so out against angle 16. Any water that is carenter the second enlarged space beyondthis angle and again be subjected to a decrease in to V ried around the free edge of angle 16 will.

angle 16 were entirely omitted the formation f 3 of the enlarged space on the side of the sash plate Would in itself cause a reduction in velocity and accomplish a part of the desired result, but it is much better to have the air current given a definite change in direction Within this space, and this is done by the angle iron 16.

What I claim is:

1. In a Window of the type havingjambs, openings through the inner Walls of the 1 jarnlo's, 'abaffle forming part "of the inner jainb Wall "between such openings, separate enlarged chambers back of such openings and sashes having plates adapted to extend through such openings, and sealing members 15 Within the jamb carried by a sash adapted to Contact 'n ith-the rear wall of the baffle and each adapted to contact witha sash plate at two points 'on theoutdoors side of such sash plate-and to-i orm an enlarged spac'e adjacent such sash plate between "such "points ofcontact.

2. A structure'as specified in claim 1, Which further includes means for giving :air' cur- "rents which enter such enlarged space a-definite change of direction in the horizontal pl'ane.

A structure as specified "in claim 1 "which further includes 'means which contactswiththe sash plate and enters s'uchenlarged space and therebypreventsair 'cur-- rents from passing directly through such enlarged space. e,
